When discussing liquid waterproofing, it is easy to place all systems into a single category.
In reality, liquid waterproofing technologies can differ significantly in terms of performance, flexibility, installation methods and intended applications.
Some systems rely on reinforced laminates to provide mechanical strength and durability.
Others focus on flexibility, crack-bridging performance, rapid curing or resistance to demanding service conditions.
Common technologies found across the industry include
- Reinforced fibreglass systems (GRP)
- Polyurethane-based membranes (PU)
- PMMA technologies
- Polyurea systems
Each technology offers different advantages depending on
- Roof design
- Substrate condition
- Structural movement
- Detailing complexity
- Installation constraints
- Expected service life
There is rarely a universal "best" waterproofing system.
The most successful projects are usually those where the technology has been selected to suit the specific requirements of the roof rather than applying the same solution to every project.
Understanding the differences between these technologies is often the first step towards achieving long-term waterproofing performance.
The right system. For the right roof.
Technology should follow project requirements.
